Job
Lubricator, stuffing box, BOP, pressure test and O-rings
The lubricator is long enough for the tool string, with room to close the well
The stuffing box packing matches this wire and is not worn through
The BOP rams match the wire size and close by hand before the job
The pressure test is written down, is above the expected well pressure, and held with no weep
O-rings on the unions and crossovers are the right kind, undamaged, and seated
